GluttonTM Neurovascular Aspiration Catheter is indicated in patients with AIS who have a large vessel occlusion (LVO). Large vessel occlusion refers to the occlusion of a major cerebral artery such as the middle cerebral artery or the internal carotid artery. Patients with LVO typically have severe neurologic deficits and poor clinical outcomes. Mechanical thrombectomy using an aspiration catheter is preferred over intravenous thrombolysis as it is more effective in restoring blood flow to the affected area. Moreover, it has been shown to be safe and feasible in both anterior and posterior circulation. The neurovascular aspiration catheter has several advantages over other mechanical thrombectomy devices. Firstly, it allows for quick, complete, and secure clot removal. The aspiration catheter creates a suction force that can remove the thrombus in one piece, thereby minimizing the risk of distal embolization. Moreover, the aspiration catheter can be used with a stent retriever in a technique known as aspiration first, then retriever. This technique has been shown to enhance the efficacy of clot removal and improve clinical outcomes. Secondly, the aspiration catheter has a lower risk of vessel injury and perforation compared to other mechanical thrombectomy devices. It does not require aggressive manipulation or deployment of the device, thereby minimizing the risk of vessel injury. Thirdly, the aspiration catheter can be easily maneuvered within the cerebral vasculature, allowing for access to distal and tortuous vessels. The Glutton works by creating a suction force via a syringe or an aspiration pump. The catheter is inserted through a femoral artery and navigated to the occlusion site via a guide wire. Once in position, the catheter is advanced through the clot until it reaches the distal end. The operator then creates a vacuum by aspirating blood into the syringe or pump. The clot is then aspirated into the catheter and removed from the vessel. The procedure can be repeated until complete recanalization is achieved.
Features&Advantages
1. The hydrophilic super-slippery coating on the Neurovascular Aspiration Catheter is not only beneficial to the neurosurgeon but also to the patient. This is because it reduces the amount of time needed for the neurosurgical procedure and minimizes the risk of damage to the blood vessels and surrounding tissues.
2. It is specially designed to have a very large inner diameter (0.072 inches) which enables efficient suction of clot material while simultaneously providing support to the catheter pathway.
3. The distal multi-segment hardness gradient design of the catheter improves the flexibility of the device while maintaining its strength. This allows the catheter to reach deeper into the brain to remove blood clots without causing damage to the delicate blood vessels.
4. The polymer composite material is designed to enhance the pushability of the catheter, allowing it to navigate through the tortuous, narrow vessels of the brain more easily. This material is a blend of various polymers that work together to increase the stiffness and torsional rigidity of the catheter.
5. It is made up of a coil and braiding that work together to provide maximum flexibility and maneuverability. The coil provides the catheter with the flexibility needed to navigate through the complex anatomy of the brain's blood vessels, while the braiding gives it the strength and support needed to withstand the forces of aspiration.
